Enterostatin is an endogenous pentapeptide fragment involved in the regulation of food intake.1 It is released from its precursor protein, procolipase, during digestion and acts in the peripheral and central nervous systems to reduce food, especially fat, intake through the vagus nerve in the periphery and κ-opioid-, serotonin (5-HT) receptor subtype 5-HT1B-, and cholecystokinin-mediated signaling pathways in the brain.1,2 Enterostatin binds to mitochondrial complex V, also known as F1F0 ATP synthase, in a cell-free assay and inhibits ATP production and increases thermogenesis in INS-1 insulinoma cells.3 It reduces body weight in rats fed a high-fat diet but not mice fed a chow diet. Enterostatin (1 nmol, i.c.v) reduces food intake in wild-type, but not melanocortin receptor 4 knockout (Mc4r-/-), mice.4 It also enhances memory consolidation in mice in a passive avoidance test when administered at a dose of 300 mg/kg, an effect that can be blocked by the cholecystokinin 1 (CCK1) receptor antagonist lorglumide .5

| General tips | Please select the appropriate solvent to prepare the stock solution according to the
solubility of the product in different solvents; once the solution is prepared, please store it in
separate packages to avoid product failure caused by repeated freezing and thawing.Storage method
and period of the stock solution: When stored at -80°C, please use it within 6 months; when stored
at -20°C, please use it within 1 month. To increase solubility, heat the tube to 37°C and then oscillate in an ultrasonic bath for some time. |

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )
Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.
Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.
Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
